Description

Technical Field

[0001] This utility model relates to mechanical equipment for the production of vibration dampers, and more particularly to a loading and unloading device adapted to a vibration damper indicator machine. Background Technology

[0002] With the rapid development of the automotive industry and the continuous expansion of the shock absorber market, the demand for shock absorbers is constantly increasing, which is prompting the manufacturing process of shock absorbers to move towards automation.

[0003] Before leaving the factory, shock absorbers need to be installed in a dynamometer to simulate the dynamic loads they experience during vehicle operation. This allows for precise testing and evaluation of the shock absorbers' performance, ensuring they meet design requirements and quality standards. Previously, shock absorbers were manually placed onto the dynamometer's unloading platform. With increased shock absorber production, this step has been gradually replaced by automated equipment. Existing automated equipment uses automated grippers to pick up the shock absorbers and place them onto the dynamometer's unloading platform, thus automating the unloading process during shock absorber testing. However, some shortcomings still exist:

[0004] 1) Existing technology uses parallel grippers to hold the shock absorber. The cylinder clamping force is small, the accuracy is not high, and the standard gripper is too expensive.

[0005] 2) Due to the difficulty in controlling the error of incoming materials, the bottom of the vibration damper is prone to scraping against the feeding table on the indicator machine during the feeding process, causing damage to the surface paint and affecting the feeding accuracy. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this utility model provides a loading and unloading device adapted to a vibration damper indicator machine. This loading and unloading device has a large clamping force, ensuring the stability of the workpiece during the unloading process. Simultaneously, during unloading, the device places the workpiece on the indicator machine's unloading platform, then releases it. After inspection, the workpiece is clamped and lifted for removal. During loading and unloading, the bottom of the workpiece is prevented from scraping against the unloading platform on the indicator machine, effectively protecting the paint and eliminating the influence of incoming material errors, improving unloading accuracy and preventing subsequent automated operations from being affected by unloading accuracy issues.

[0007] The technical solution of this utility model is as follows:

[0008] A loading and unloading device adapted to a shock absorber indicator machine includes a frame; the frame is provided with an extension mechanism, which is connected to a clamping mechanism, and the clamping mechanism is provided with a lifting mechanism; the extension mechanism includes an extension cylinder mounting plate and an extension cylinder, the extension cylinder mounting plate is connected to the frame, the extension cylinder is fixed to the extension cylinder mounting plate, and the extension cylinder can drive the clamping mechanism to extend forward; the clamping mechanism includes a clamping mechanism mounting frame; the clamping mechanism mounting frame is provided with a clamping block assembly mounting plate, the clamping block assembly mounting plate is provided with a clamping block slide rail, and two sets of clamping block assemblies are provided on the clamping block slide rail; a lifting cylinder is provided at the bottom of the clamping mechanism mounting frame. The piston rod of the lifting cylinder is connected to the connecting block inside the clamping mechanism mounting frame. The connecting block has connecting rods at both ends. One end of each connecting rod is hinged to the connecting block, and the other end is hinged to the clamping block assembly. The lifting cylinder can drive the connecting block to move upwards, causing the two clamping block assemblies to continuously approach each other on the clamping block slide rail, thereby clamping the workpiece. The lifting mechanism includes a lifting cylinder, a lifting block, and a cam follower. The lifting cylinder is located at the top of the clamping mechanism mounting frame. The piston rod of the lifting cylinder is connected to the lifting block. The lifting block has a lifting groove, which cooperates with the cam follower. The lifting cylinder can push the lifting block, thereby driving the cam follower to lift the clamping mechanism.

[0009] Compared with existing technologies, this utility model, through a specific structural design, improves the stability during clamping and unloading, eliminates the influence of incoming material errors, and improves unloading accuracy, achieving significant progress, as detailed below:

[0010] 1) The loading and unloading device of this utility model connects the piston rod of the lifting cylinder to the connecting block, and the connecting block is connected to the clamping block assembly through the connecting rod. This structure can convert the vertical movement of the lifting cylinder into the horizontal movement of the clamping block, thereby achieving workpiece clamping. The clamping force is large, which improves the stability of workpiece clamping.

[0011] 2) The loading and unloading device of this utility model achieves the lifting of the clamping mechanism through the cooperation of the lifting groove and the cam follower, which can lift the clamping mechanism before clamping the workpiece; during unloading, the clamping mechanism is naturally lowered under the action of gravity, placing the workpiece on the inspection table, ensuring the accuracy and stability of the workpiece unloading, eliminating the influence of incoming material error, avoiding the bottom of the vibration damper from rubbing against the unloading table on the indicator machine, and effectively protecting the paint; after the inspection is completed, the workpiece is clamped and lifted out, which also plays the role of protecting the paint.

[0012] Furthermore, in the aforementioned loading and unloading device adapted to the shock absorber indicator machine, the extension mechanism further includes a movable frame; the movable frame includes a movable plate and a group of movable columns, the movable plate is connected to the piston rod of the extension cylinder, and the movable columns pass through the extension cylinder mounting plate and are connected to the movable plate. The movable frame can bear the weight of the clamping mechanism and the workpiece, avoiding excessive load on the extension cylinder, and improving the stability of the extension mechanism. Furthermore, a guide plate is fixed on the movable plate, and the cam follower is located at the top of the guide plate; a sliding block is fixed on the clamping mechanism mounting frame, and the guide plate and the sliding block slide together, enabling the clamping mechanism to move vertically. The lifting of the clamping mechanism is achieved through the cooperation of the guide plate and the sliding block, resulting in a simple structure and ease of implementation.

[0013] Furthermore, in the aforementioned loading and unloading device adapted to the shock absorber indicator machine, the clamping mechanism mounting frame is provided with a limiting block, and the lifting block is located within the limiting block. The lifting block can slide within the limiting block under the drive of the lifting cylinder. The limiting block can interact with the lifting block during lifting to complete the lifting, bear the load of the piston rod of the lifting cylinder, prevent the lifting cylinder from being damaged due to excessive load during the lifting process, and extend its service life.

[0014] Furthermore, in the aforementioned loading and unloading device adapted to the vibration damper indicator machine, the frame is provided with a vertical slide groove, and the extension cylinder mounting plate cooperates with the vertical slide groove, allowing it to slide within the vertical slide groove. Limiting holes are distributed outside the vertical slide groove, and bolt pairs are provided within the limiting holes. The extension cylinder mounting plate is fixed by the cooperation of the bolt pairs and the limiting holes. The vertical slide groove allows for adjustment of the height of the clamping mechanism, making this invention applicable to more workpieces of different sizes and types, thus broadening its scope of application. In addition, the use of limiting holes and bolt pairs to fix the extension cylinder mounting plate is easy to implement. Furthermore, it also includes a height adjustment mechanism; the height adjustment mechanism includes an adjusting handwheel, a threaded lifting rod, and a lifting rod nut. The lifting rod nut is fixedly connected to the frame, located outside the threaded lifting rod, and connected to it via threads. A pressure plate is provided on the extension cylinder mounting plate, and the lower end face of the threaded lifting rod abuts against the pressure plate. The upper end of the threaded lifting rod is connected to the adjusting handwheel, allowing adjustment of the threaded lifting rod's vertical position. The height adjustment mechanism can adjust the threaded lifting rod according to the height of the extension mechanism, pressing it against the pressure plate, thereby further fixing the extension cylinder mounting plate. This improves the stability of the device and prevents it from shaking during operation, which could affect the material feeding accuracy.

[0015] Furthermore, in the loading and unloading device adapted to the aforementioned vibration damper indicator machine, the clamping block assembly includes a clamping block, which is V-shaped. The V-shaped design can cooperate with the workpiece, which is beneficial for clamping the workpiece and improving stability.

[0016] Furthermore, in the loading and unloading device adapted to the above-mentioned shock absorber indicator machine, the clamping mechanism mounting frame is equipped with a photoelectric sensor, which can detect the workpiece when the workpiece enters the designated clamping position.

[0017] Furthermore, in the loading and unloading device adapted to the aforementioned vibration damper indicator machine, the clamping mechanism mounting frame is provided with a connecting block groove, and the connecting block is provided with a protrusion located within the connecting block groove, allowing it to slide within the groove. The connecting block groove provides a clear sliding path for the connecting block, enabling it to slide smoothly along the groove and improving the stability of clamping the workpiece.

Before clamping the workpiece 21, the lifting mechanism is in a lifted state. During unloading, the lifting cylinder 10 retracts, and the clamping mechanism naturally descends under gravity, placing the workpiece 21 on the testing table of the indicator machine. The workpiece 21 is then released, thus completing the unloading process. After testing, the clamping mechanism clamps the workpiece 21, then the lifting cylinder 10 extends, the lifting block 11 moves forward, driving the cam follower 12, and thus lifting the workpiece 21.

This improves the stability of the device and prevents it from shaking during operation, which could affect the material feeding accuracy.

[0038] In this embodiment, the clamping block assembly 9 includes a clamping block 901, which is V-shaped. The V-shaped design can cooperate with the workpiece 21, which is beneficial for clamping the workpiece 21 and improving stability.
